Video/Audio Delivery Questions

Hi Everyone-
I'm really excited about the possibilities of Adobe AIR,
specifically to further our vision of desktop, content rich apps
with video/audio, as well as taking that capability to digital
signage.
Just a few questions:
- Does Adobe offer an 'out of the box' solution like they use
in the Media Player?
- How difficult is it to develop an AIR app similar to the
examples by AOL and Yahoo?
- What experience will developers need to create it?
(laungauges, etc.)
Any help you can provide is appreciated. This ia a great
technology we'd like to take advantage of.

Needing a mini to video/audio edit/produce.

been digging deeper and deeper into video and audio production and editing.
currently im running a 24" imac 2.4ghz, 1gb ram, i use it as my everyday computer and i been playing around with some video editing and a good bit of audio production. (im going to eventually upgrade the ram in this thing)
my question is, im looking to pick up a mac mini and run a dual display. this mini will ONLY be used for video and audio production. the video production i might add is nothing very over the top. just your simple credits, adding music, and clipping scenes. (im producing some how-to halloween prop dvd's and haunted house walk through) for audio production again, nothing very over the top.
im looking to pick up a mini due to the price. a mac pro is way out of my price range.
what do you think would be the best route mini wise to go for? 2.66? thinking my 2.4 has been working fine a 2.53 should be fine? and as for the ram. i planned on upgrading the ram to around 4 or even 8 gigs in the future. for the hard drive space, for movies and audio production im going to need something decent in size. thinking 500gigs i could always do something external in the future?
i was also pondering the mini server, 2 500 gigs with 4gig ram and 2.53mhz. BUT lacking a super drive thats really no problem because im running an external lacie lightscribe.
so im asking you guys/gals what would be the best route for me to take, price wise and bang for my buck to create a nice little video/audio machine?

I also bought a new 3.06 Mhz IMac 21.5 in IMAC this spring. I was unfamiliar with the new miniport. I was on the phone with Apple Sales for buying a new MacBookPro and while ordering wanted to add on the cables necessary to accomplish connecting my new IMAC to my HDMI tv. I have been accustomed to connecting my old g4 laptop with adaptors and a long cable on end is HDMI and the other connects right into the video port out on my laptop. But the older method leaves you without sound.
So...the Apple guy is in a hurry to sell me a computer and insists there is no Apple IMAC or MacBookPro which will work with video and sound to HDMI. I had the item in my inbasket at MacMall. I may be wrong. But I gave up on ordering it. I picked up an HDMI to HDMI extension cord at Best Buy and ordered the Mini video adapter to HDMI connector from Apple store. I haven't opened it yet or set it up. But what does one need to buy to make this work. Since the guy didn't help me. I had to buy it online separately. And since I had ready acct with Apple , just bought it there although it was about 15% cheaper at MCMALL.
Please someone in the know or who watches their computer on their HDMI TV help tell me what cables to buy and where to connect them to my tv. I have a Sony Bravia and it has an internet thing on the side. I haven't used it for anything yet. I have cable/dvr,blue ray dvd, and input from laptop.
Thanks in advance. Rheta in San Diego

Insufficient Bandwidth when trying for video/audio chat?

When my Dad is away, I like to talk to him on iChat.
When my Dad tries to invite me to a video/audio chat, it comes up with a message, saying: insufficient bandwidth to run this conference.
I have tried altering the bandwidth on Preferences, but it doesn't seem to work!?!?!
Any answers to my question?
Thanks.

IChat AV 3.0.1 - Help. Can't Video/Audio

Power Mac G5 Quad Mac OS X (10.4.4) Here's my set up: Power Mac G5 (Brand New iSight Camera as of Jan 20, 2005) SpeedStream DSL Modem from SBC. I do not have my FireWall on.
Here's the problem: When a buddy trys to contact me for a Vdieo/Audio call I click their invitation video icon and my video windo pops up and I can see my pretty mug smiling and waiting for the call. At the bottom of the video image is a black rectangle which reads ' PREVIEW' . Anyway, I accept the call by clicking 'Accept'. In the transparent original invitation menu desplayed at the top of the video image it reads: Starting Video call from: [email protected] and on the right side of this menu bar is the Apple gray spinning Gear - which spins and spins and spins. I've let it spin for 5 minutes and nothing happens. I bet I could let it spin forever. The same thing happens when I try and contact someone.
No my friend on the other line said that al he got was a gray video image coming from me.
Well, that's it. Any help would be great. Thanks!
TC

Hi everyone,
I might have solved the problem. I did change my PPPoE so my computer would handle the PPPoE connection and not my SBC SpeedStream modem. However, I still had the very same problem as before. I could not Video or Audio chat. I could send and receive files and text chat. As well, when I was invited to a Video or Audio chat when I accpeted the Apple Spinning Gear would just spin and spin and spin, forever if I let it.
That being said, my friend in San Fran who was helping me sent me his iChat AV 3.1.1 (I had iChat AV 3.0.1) as soon as I downloaded iChat AV 3.1.1 and installed it, well, I could Video and Audio. It works perfectly. My guess is the iChat AV 3.0.1 didn't have the correct drivers for my Brand New iSight and the iChat AV 3.1.1 did. Anyway, my friend and I Video/Audio chated for about an hour with no pause or break...
Now, I just need to know if my original modem setting will work for the iChat AV 3.1.1 - until I test this I won't say my question is answered just quite yet...

IChat Video/audio preferences hangs up

heLLo,
Recently, whenever I wanna change the preferences of the video or audio (let's say change the bandwidth or output) this windo hangs up for about a good minute, which rather longer than expected!!! Why??
I only have conference recorder & iGlasses installed on it, and I don't think it did anything to it, as I've uninstalled them already to test: no success.
I've tried to trash the pref files, but nothing. I might have to reinstall it with pacifist.
Thanx

Chris,
thanx, but I've done all that already.
But it seems I might have found what the problem could be:
I use a D-Link Bluetooth USB , and I think for some reasons, if I wanna go in the system Pref in Bluetooth, it just hangs up. Same if I wanna connect Address Book with bluetooth, hangs up. So I disconnect the D-Link Bluetooth USB , and replug it, and works fine for a while until it happens again. When the bluetooth is workin, the video/audio pref in iChat are totally OK, no hangs up. (Guess when the iChat pref is looking for the bluetooth output or headset, and if the bluetooth module isn't properly working, then it might cause the hangs up).
Now, why do my D-Link Bluetooth USB is doing that is another question. It simply plugged on USB2 hub (with AC adapter). So I might try to plug it straight at the backof the iMac to test.
I've just trashed the Bluetooth pref (the com.apple.Bluetooth.plist one, are there any other I should trash?)
Thanx. The Hunt carries on

Video (or Video + Audio) Data Rate

Wondered if anyone here might know of a software utility that has the ability to scan QuickTime compatible files and either display the video (or video + audio) data rate excursion or, as an alternative, graph the instantaneous variation in the data rate over time.

Apple +I (show info) in QT player will show you the framerate and bitrate while playing.
Thanks for your suggestion, Rick. However, I must point out that the data rate so displayed is simply the total average for the entire clip and not the instantaneous (i.e., constantly changing) variance with time. Preliminary observations tend to indicate the single pass H.264 algorithm begings roughly 10% under the requested data rate and quickly settles very near the target. The multipass algorithm, on the other hand, appears to begin in the vicinity of 300% above the targeed data rate and monotonically decreases throughout the remainder of the movie clip. So much for a quick qualitative analysis based on observations during the actualy encoding process.
What I now wish to do is actually perform a bit of quantitative analysis and, based on those results, correlate actual data rates with the ability of a given H.264 multipass file to sync to an iPod. Basically, I am trying to determine whether or not a user data rate input is used as a comparator during the initial phase of multipass H.264 coding and, if so, how it is implemented. (I.e., how are the delta values handled -- linearly, exponentially, etc.) In addition, I wish to compare QT v7.0.3 with v7.0.4 clips to determine why the latter are less iPod compatible. Too, there remains a question as to whether or not any data rate information is now embedded in the clips themselves since various work arounds tried (i.e., clipping file lengths) have proven unsuccessful.

Ridiculously simple audio editing question for Garage Band

Ok, so this is really a fundamental
question. It concerns editing technique.
In analog mixing, the editor put
the sounds to be saved in the right
places on each of several tracks --
narration, sound effects, lip sync,
music, etc. The tracks were then
all locked together and the mixer
adjusted the volumes to either save
or reject audio information.
A blank master received the information
and that was your final product,
in sync, sprocket by sprocket, with
the video.
My question, then, is, how do you
do it in digital multitrack such as
Garage Band? Are you aiming to have
4 or 5 tracks all level controlled
or do you simple erase unwanted
sound, or what exactly do you do,
in post production? If you are going
to do a voice over, then you have to
do a mix at some point, not just a
cut and paste. What's the philosophy,
if you don't mind my asking?
Thanks,
Ed

Wow... you gave me flashbacks to a movie soundtrack I scored, with separate reels of tape all synced up and whirling away for final mixdown!
To answer your question as best I can in a paragraph or two, digital mixing is unlimited compared to analog. Whereas tape has a physical limit, you can always add another digital track (there are limitations to digital, but they are becoming harder to reach as systems become increasingly powerful). So no need to erase. Editing is also a breeze. Digital tracks are endlessly malleable, with virtually every parameter available for automation.
Sometimes you might mix down to stems or mix everything down to a stereo master (or alternative mixes) for post production. Similarly, in post, they can deal with huge numbers of digital tracks from different sources.
In terms of a professional workflow, Logic is the more typical choice over Garageband, and includes a number of features designed for scoring to picture: variable sample rates, frame rates, etc.
Gain staging in digital recording is different than in analog, and it requires a different approach to achieve excellent sounding results. But the digital workflow is so much more flexible, forgiving, and economical, that it has been the death-knell for the analog workflow. Infinite bussing, routing, mixing, comping, storing, stemming... infinite possibilities, really!

How do I restore my video/audio in the Timeline of my project?

The whole timeline has windows that are red that say Media Offline. Where did my video/audio go??
Where do I find it? How do I restore it into the timeline I was working on with the project. When I open the project I also get a question that wants to know where is a specific file pertaining to this project.

Or, was it on a DVD, that you Imported directly, and now that DVD is not in the drive/burner?
When media is listed as Off-line, just as Steve mentions, the link between the Project file (.PREL) has been broken. This can happen, when one Moves files, Renames files, or those files are, for some other reason, not where the program last saw them. This ARTICLE will give you a bit more background on the .PREL files, plus some tips on Save/Save_As, etc.
Usually, one gets warning messages, and PrE will help you locate your files. It does a good job of this. Did you get any messages, when you Opened this Project? Did you Move, or Rename any media files?
Good luck,
Hunt

Not able to recognize any video/audio devices using jmf and java soun

Hi ,
I need one help from your side.
Here I am expecting some clarifications from you. Before that let you my environement.
My working environment :
Eclipse tool and added jmf jar to my project I did not do any thing more.
If any thing I need to do just let me know. My target platform is MAC & UBUNTU.
Please bare with my questions.
1) I am not able to recognize any video/audio devices using jmf and java sound APIs on My system.
( I checked with the app mentioned in the http://www.java-forums.org/new-java/11201-jmf-cannot-connect-device.html )
Do we need any administrives rights for our working PC.
What is the procedure/ setup I need to follow from a java application to enable particular audio/video device since I dont about end-user system setup right.
If possible send some sample code to recognize /r detect audio device ( voice input ). It should run on both MAC and UBUNTU.
2) I run the one sample audio recording application of this link (http://www.jsresources.org/examples/SimpleAudioRecorder.java.html) which is provided by YOU.
I got output audio file and able to hear voice on UBUNTU system but not able to hear voice on MAC system.
I heared that default line in ( audio setup of the sys) is wont take any voice data on MAC.Why I made this stmt means we are getting false when using isSupported methods of JAVA SOUND API.
( like for TragetdataLine ...i,e, all ports are getting false)
I have one sample audio recording app implemented by QUICKTIME API. In this case also he taking audio ftom device only using quicetime API.
With that we are able to record and hear audio ( voice input --> not line in , external device we added some thing like SSB...)
3) In case of Video capturing DataSource, Streams are implemented by PullBufferDataSource , PullBufferStream intefaces used.
In case of Audio capturing DataSource, Streams are implemented by PushBufferDataSource, PushBufferStream intefaces used.
Can you explain the reasons ? I gone through API but i am not clear.
HOPE I WILL BE CLARIFIED EVERY THING FROM YOU.
Thanks

Daily Digital Video School Announcements- Question!

Okay. At the moment, out media class is producing our daily announcements via video mixer and vcr. Until recently we've discovered that we have the equipment to broadcast the announcements digitally from a computer. So the question is, what do we need to use to connect our video to our computer? We would still like to use the mixer. It has a DV output. It is the MX-Pro DV 4. However, we would like to send the video/audio to the computer from the cable that is currently running to the VCR. So what do we need to convert a regular cable to the computer?

Sorry. We want to simoultaneously send it to the vcr and the computer. We tried using the DV connection on the mixer but it didn't work with iMovie. We contacted the mixer company and they said it is only configured to work with some random version of Final Cut Pro and we don't have it nor are we getting it. We have the splitters for the cable and the cables, we just don't know how to connect the cable to the computer. What we are really looking for is almost recommendations for products. I guess. Anything. Anything Apple carries?

Video & audio iChat to PC

Hi,
After browsing the discussions and support areas I am still confused as to whether I should be able to conduct a video & audio conference with iChat using my iSight, iChat and an AIM account with a PC user. I am currently running OS X 10.3.4 and iChat 3.1 but cannot conference family members using iChat.
My questions are:
1. Should I be able to conduct simultaneous video and audio conferencing from my powerbook using iChat and AIM with a PC user with AIM?
2. If the answer to '1' is no then what is the best way of achieving such conferencing?
Regards Colin

Hi Jyce,
Check this FAQ
Also see my page 12

How to get video/audio metadata

Hi there, i need to get video or audio metadata in my web application. i've been searching in google but i couldn't find anything.
Is there any java metadata extractor (opensource , jar file, or method except jmf) which can support video file formats in jsp? like get bitrate, get framerate, get videoduration, etc..
thx a lot..

Video/audio chat not connecting

Okay, so this question has been asked about a thousand times here, but I can't find an answer that solves my problem:
When attempting to iChat with video or audio, both me and my buddy recieve the "fail to respond" message.
I'm using an iMac at home w/built-in camera. Hooked up to internet with Clearwire (ethernet from the modem to iMac).
Buddy is using an iBook or Mac Mini. Won't work with either of them. (I've had this happen with my PC pal and he blames my using a Mac--sheesh.) However, my other iMac at my company office (also with built-in camera) DOES allow for succesful video/audio chats with my above-mentioned buddy, so I presume that his end is OK.
I've spoken with Clearwire and they say they do not have Firewalls set up, while my buddy had to turn his ISP's firewalls off via some kind of configuration at the ISPs website. After that, we were able to get that work-iMac-to-both-his-Macs thing working.
So, gang, what is it? Do I have to tweak an iChat pref, or a Network pref, or a Sharing pref, or something else? My company iMac works fine but my home iMac doesn't. Same Macs, different ISPs.
Please hold off on the "me-too" comments and respond only with possible solutions with actual routines to try. Thanks!
iMac G5/2.1 ghz w/camera Mac OS X (10.4.5)

Hi Tony:
Thanks for the lead. I went to the discussion, printed it out and if I read it correctly, it seems that Clearwire won't allow me to set up a video chat. Is that true?
If not, and it is possible to use my Clearwire connection, what is the procedure for me to go in and make the alterations?
Thanks again!

Use two streams to manager client video/audio,Can i combine streams and record it with server AS API

Use two streams to manager client video/audio,Can i combine streams and record it with server AS API
I tried Stream.play()
var s=Stream.get("combine");
s.play("video");
s.play("audio",null,null,false);
s.record("append");
it's don't work!!

Thanks, that's what I had thought. Our domain.com zone is sourced internally and replicated to our advertisers for external users, so there's no way to change the result for internal vs external users.
This is a rudimentary question that I should already know but I sort of inherited this after it was built: Can I have users sign in with their email address ([email protected]) but under the hood, their SIP address is [email protected]? This would let users
sign in with an address they expect, but it would take advantage of the the local lyncdiscoverinternal record.
Thanks,

Recording video/audio files using Flash Meida Server through rmtp, and allow users to access the recorded files through http.

As titled, what is the way to record video/audio files using Flash Meida Server through rmtp, and allow users to access the recorded files through http?
What I am trying to do, is to record a user's microphone's input and save it to the server. Afterwards, I would like other users to be able to access the recorded files and mainuplating the audio data, by computeSpectrum(), to do some visualization of the audio. As I know computeSpectrum() cannot work on streaming files, so I think I need to access the recorded files using http instead of rmtp. Is that true?
How can I redirect the http request to the files I was recorded into my applications/appName folder? Or I need to somehow moved the recorded files to the /webroot folder?
Thanks!

I probably have asked a stupid question.
My recorded streams are still saved in the applications/appName/streams folder.
And I redirect the www.mydomain.com/streams to point to the applications/appName/streams folder.
And the rmtp recorded streams are abled to connect through http now.
